Abstract: PURPOSE:To join a semiconductor laser element and a heat dissipating body together without adversely affecting the element in characteristics by a method wherein superfine powder of Au is press-molded into a foil which can be joined to both an electrode and a metal layer by diffusion when it is placed between them. CONSTITUTION:Metal superfine powder drops remarkably in melting point as compared with a rolled piece of the same material, which occurs basing on a fact that the higher surface atoms become in energy level, the finer powder becomes and resultantly turbulence is induced in crystal lattice by small energy. Therefore, superfine powder of Au is formed into a foil 9, and when the foil 9 is sandwiched as a brazing material between an electrode 3 of a semiconductor element 1 and a metal layer 6 of a heat dissipating body 5, Au contained in the electrode 3 and the metal layer 6 and Au of the foil are actively diffused into each other's solid bodies at a temperature much lower than a melting point of Au, so that diffused junction takes place to form them into an integral structure. By this setup, a brazing material is not required to be fused and molten brazing material is prevented from flowing out, so that junction high in accuracy can be realized.
